Embodiment Construction

[0018] The feed nozzle assembly of the present invention is a simple but extremely effective means of preventing the problems associated with the use of only one feed nozzle, while surprisingly, teaching throws aside the accepted knowledge that "spray" is atomized. Convergence of the liquid feed stream is unacceptable and automatically increases the size of the droplets, improving poor conversion and overall process performance. It has now been found that by suitably adjusting the number of feed nozzles and their positioning relative to each other, and taking into account the characteristics of each feed nozzle with respect to maximum feed velocity, hole configuration and ultimately spray pattern, the spray can be The impingement is done in such a way as to balance the impact breakage and coalescence of the droplets to ensure the desired droplet size for a given operation while maximizing the potential feed stream input rate.

[0019] Impact obviously requires at least two spr...

Abstract

A feed nozzle assembly suitable for use in synthesis and combustion reactions involving gas / liquid reaction systems comprises a plurality of nozzles positioned such that their sprays impinge upon one another to obtain improved, or maintain acceptable, drop size, measured as Sauter mean diameter, by suitably balancing impact destruction and coalescence of drops. This feed nozzle assembly can be incorporated into a burner apparatus combining annular areas with stepped extended barriers for feeding oxygen and moderator gas, e.g., steam, all preferably within an exterior annular cooling means such as a water jacket.

Description

[0001] priority [0002] This application claims the benefit of US Application No. 11 / 030,925, filed January 6,2005. technical field [0003] The present invention relates to feed nozzles, and more particularly, to feed nozzles for various gas / liquid reactions, including chemical synthesis reactions as well as combustion and other oxidation reactions, wherein the feed nozzles are burner devices a part of. Background technique [0004] Various related industries use the reaction of gas / liquid systems to achieve a desired end result. These include, for example, waste reduction industries that rely on combustion for energy, chemical manufacturing industries, gas manufacturing industries, and energy related industries. Each of these industries generally conducts this reaction by finely atomizing one or more liquid streams, usually in an area of ​​elevated temperature. In the case of gasification reactions, both atomization and higher temperatures are used to facilitate liquid...
